so is the s1 the rev up motor???????????

 

S1 is not a rev-up motor... those S1 cams are wilder than the rev-up's

The main differences between S1 and the normal engine are cams, VTC units, valve springs, rod bolts and the intake system... of course.... tuned with a nice ECU

You will need to go beyond S1 to achieve 320WHP... and that will involve high compression pistons and stronger internals (rods and valvetrains)...
